I have used Holland Computers for many orders and your statement is BS.
They are one of the few that have real technical support and great customer service.
Many game part suppliers don't have a phone number let alone real customer service.
They only time they charge a restocking fee is when you return a board that does not have anything wrong with it.
There track balls are designed for the 60-in-1 and plug right in without any wiring at all:

The only thing is you need to order the mounting plate otherwise it is hard to mount it.

There 60-in-1 PCB are great as they test them prior to shipping:

I have retrofitted and build well over sixty systems with there parts and have had no issues with them at all, as a matter of fact they help me with technical issues when I was green to the industry.
Almost forgot, they offer each customer a 20% off on their first order or you can use the discount once on a larger order – There discount code is BIGTWENTY
I only paid $75 for my 60-in-1 PCB and that included shipping!
My hat off to Holland Computers and there team! You guy rock!
